Part of what we do here is making people, both audiophiles and not, grin from ear to ear and say over and over, “I never heard that before!”. There you have, musicians and hi-fi enthusiasts, the absolute best high-end tube amplifiers on the market today. When higher-fidelity is the goal, certain aspects of the music listening experience become important. none Explore Nelson Ng's board "Hi End", followed by 129 people on Pinterest. It can be mounted without isolation pads for better thermal conductance, but then the heat sink itself must be isolated from the metal enclosure which usually is connected to the ground.Hi end hifi Audioarts offers Goldmund, Zellaton, Thales, FM Acoustics, Linn and many other audio products. Also if the heat sink is isolated from the metal tabs of the chips with some mica pads then the heat sink is good to be connected to the ground as it induces more hum in the open inputs. But once the amplifier is connected via cable to the source and there is no signal, it becomes absolutely silent. If the input is disconnected and open there is a little hum which can be heard only with an ear pressed against the speaker. The power supply is very simple – a bridge rectifier and 4 x 10 000uF/50V capacitors. The transformer is a little weak for this amplifier, maybe 150W or 200W would be a better choice.
The test was ran with 8Ohm dummy load and the big heat sink gets only warm after hours of playing music from my computer at max volume. It can be regular electrolytic capacitor, but it’s better to use non-polarized or bipolar.
I used 47uF/63V non polarized capacitor for C2. The diameter of the wire must be minimum 0.4mm. I made the output inductance L1 by winding 15 turns of enameled wire around the resistor R7. I removed the time delay capacitor connected to MUTE pin, because it’s better to use separate DC protection schematic which has similar functionality. The schematic is based on the schematic in the datasheet of the chip with minor changes. I was pleased of the sound this chip produced the first time, so I decided to make another amplifier with it.
This project is an audio amplifier based on LM3886.
